MOLD.

- To all' whomflz't may concern:

Be it known that I, BERNARD B. BnAsz- KowsKI, a citizen of the United States, re-

I provide a mold for open-hearth furnaces in-'.

' siding at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Molds, of which the following is a specification.

This invention relates molds for use in connection with open-hearth furnaces, and. has for its object'to provide a mold for-such use, in a manner as hereinafter set forth, for making a solid ingot and overcoming piping 'to a mmimum. 1

A further object of the invention is to eluding a removable head and jacket, whereby when either or both have been injured, a new head or jacket or both can be substituted, under such conditions overcoming the necessity of discarding the body portion of the mold.

A further object of the invention is to.

provide a mold for open-hearth furnaces havinglifts arranged in a manner as hereinafter referred to, to overcome the break mg off of the mold at the top when the moldis ifted.

Further objects of the, invention are to provide a mold for use in connection with open-hearth furnaces which is slmple in its construction, strong, durable, efliclent and convenient ,in its use and comparatively 1nexpensive to'manufacture. 1 b

With the foregoing and other objects in view this invention consists of the novel construction, combination and arran ement of parts as hereinafter more speci cally described and illustrated in the accompanying drawings wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the S00 e of the claims hereunto appended.

thickness from its lower to near its upper end, or in other words the outer face of each wall of the mold inclines'upwardly and inwardly from the bottom thereof to a contmuous lateral flan e 2, at the top of the body portion 1. T e flange 2,. is cutaway to provide 'a'peripheral shoulder or ledge 3. The inner face of each of the walls of the bodyportion 1 is plane throughout, with the exception that in proximity to the top thereof such face :is cutaway to form a shoulder or ledge 4, to supportthe brick,

not shown, which extends into the head. The

jacket 6 extends to and isflush-with the shoulder or ledge 4, and its top edge is used in connection with the shoulder or ledge 4, to support the brick, not shown.

v The jacket 6 projects below the body portion 1, and is inclosed by a collar 5, which abuts against the lower end of the body portion 1 and the shoulder 9. The body portionL-has a plurality of pockets 11, with which communicate openings 12, these latter registering with slots 13, formed in the collar 5. The slots 13, open into pockets 14. The pocketsll, openings 12,'slots 13 and pockets 14, are provided for the purposeof positioning connecting bolts 15, relative to the body portion 1, and collar 5, whereby the latter will be connected to the former.

Mounted upon the shoulder or ledge 3, is a removable rectan ular head 16, formed of cast iron and whic incloses the major porgi on of the flange 2, as clearly shown in Upwardly extending yokes 17-, are provided in the top edge of the head 16, to

facilitate the removal and replacements of said head 16, when required.

Arranged below the flange 2, are laterally pro ecting apertured lugs 18, to which are pivotally connected as at 19, yokes 20,

to facilitate the shifting of the body portion 1, when required.

The lugs 18, are arranged below the flange body portion 1 is lifted the weight is oil flange 2, preventing the possibility of breaking of sa d flange 2, and by such an arrangement when the The top edge of the jacket 6, and the ledge 4, supports a body of brick which is extended into the head 16, and forms a continuation of the moldin chamber, charcoal supports the brick for t e purpose of keeping it hot-so that when the metal runs into the head it will not cool rapidly and piping will be prevented.

As the head is removable, it is obvious that if it becomes dama ed a new one can be substituted, under suc conditions doing away with the throwing away of the body portion as would be the case if the head were an integral art of the body portion. This statement a so applies to cast iron jacket 6 if the latter should become injured.
